Re: 5400 vs 7200 rpm hard drive

It has kind of become a standard spec for laptops hard drives that you are allowed 5 volts at 500ma. This happens to be the limit for a USB port to supply power, but, this had kind of been adopted even before people began widely powering laptop hard drives from USB ports. That is 2.5 watts of power, and power = heat, directly and absolutely. So what you really get into these days is how the drives manage power, e.g. how they shut themselves down (fully or partially) when they are not being actively used, because that is where the real differences in drive power consumption and heat generation comes from these days.

I understand that 7200 rpm drives are sgnificantly faster. True?

Yes, I always upgrade my laptops, and I notice a significant increase
in speed.


One of the concerns I have is heat production.

Yeah, they do get warmer,


Is this *noticably* warmer. I mean, on top of CPU and 5400
drive, you could feel the difference by touch if you were to replace 5400 with 7200?
